Firefox, Rogers SW Ont
Clearing the cache was the first thing I tried.
It seemed to help at first, but I think it was coincidental with whatever you were doing on the server end.
The weirdness came back, pretty much as RB has described, and Remember Me doesn't, now.
I gave it a day's rest and tried again last night.
Last night and today, it's better than the past couple weeks.
Every page I've tried loads fast, except for New Posts; every page is formatted correctly except for New Posts.
Manage Attachments just won't load.
Gotta go now, have a fun day!
